IMPROVEMENT IN MACHINES FGR SETTlNG BOXES IN WHEELS.

Specification forming part of Letters Patent No. 134,091, dated December17, 1872.

To all whom it may concern:

Be it known that I, JOHN A. NnwELL, of Kalamazoo, in the county ofKalamazoo and State of Michigan, have invented a new and usefulImprovement in Machines for Setting Boxes in Wheels; and I do declarethat the following is a true and accurate description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon and being apart of this specification, in which- Figure 1is a perspective view of my invention with wheel attached; Fig. 2 is anelevation, in section, showing the split nut and its attachments; Fig. 3is the taper boring-tool and Fig. 4. is the taper reamer.

' Like letters indicate like parts in each figare.

The nature of this invention relates to an' shown in a vertical positionin the drawing,

and is composed of the four pieces marked b b b If, to which the wheelto be operated upon is secured, and which is done when the frame 0 islaid down horizontally on top of the frame B. The wheel, being laid uponthe frame 0, is centered, so that the center of the required borethrough the hub is directly in line with the center of the draw andguide nut D, which is secured to the plate E in the rear.

of the frame 0. The wheel is then fastened to the frame by means of thedog 0, which is adjustable from the center in the slot (1, the hubresting upon the cutched support h, which is also adjustable upon thebolt k, working in the transverse slot shown, and in a correspondingvertical slot in the support itself.

The wheel being thus securely fastened to the frame, the frame is raisedto a horizontal position, as shown in the drawing in Fig. 1. Theboring-tool F is then inserted through the hole in the hub until the endof the tool will enter the split guide-nut D, the two parts of whichhave been thrown apart by means of the lever H, which has two teeth, a,which engage one with each half of the nut. This boring-tool is providedwith three series of threads, t1? 21 each being larger than the oneunder it, and the cutters 1' r 1' increase in size in a like ratio, sothat the hole bored can be readily finished by the tool G provided withtaper reamers to, to a perfect taper. The outer ends of these toolsenter the opening between the two parts of the split nut, when the twoparts are closed by means of the lever H, and the threads engage withthe threads on the boring-bar, when the rotation of the latter willcause it to be drawn into the hub, and the cutters and reamers to dotheir work.

When in operation, the outer ends of the boring-tools are sustained bythe rest I, securely held in place by suitable braces.

The cutters form parts of the nuts 12 0",the

blades starting from opposite sides of the nuts,

crate substantially as and for the purposes set forth.
